Every time when you do re-calibration you shorten your battery life and capacity. Li-ion and li-polymer have only 300-500 full charge/discharge cycles. I tried to calibrate myself few times and every time I had problems after. For example, charging from 50% to full get me stuck at 85 or 90%. Only solution was to turn off phone without battery and plug battery again.

Then I've just started charging from some percent, more than 50%. Few days ago, I used my phone a lot and battery discharged to 35%. I thought, OK now I'm going to stuck to about 85% again. But guess what? No! Battery recharged to 100% as it should!

Conclusion, stop calibrating your battery and charge it more often. Once per one or two months do full discharge. Not because battery, just because Android itself.
[Atrix 4G General] terminator1983:
yes all the steps given in this thread whereas in fastboot i have not done all the commands just one fastboot -w.

I will try these commands

moto-fastboot erase boot

moto-fastboot erase system

moto-fastboot erase userdata

moto-fastboot erase cache

moto-fastboot erase webtop

moto-fastboot erase preinstall

but first i want to confirm that is it safe to use these command bcoz i don't want brick my phone.
[Atrix 4G General] xploited:
I calibrate after every rom flash and I don't have the problems you described. Also, my battery life has always been great.
[Atrix 4G General] Zeljko1234:
You "must" calibrate after flash just because of the rom, to learn you battery capacity. But for batter itself is better to charge more often then full charge cycles. Read about it if you don't believe me ;)
[Atrix 4G General] xploited:
I've had this argument with a different person at the beginning of this thread.

People that come here and use the calibration tutorial either do it because they flashed a rom or because they have battery life problems. And it solves their problems.

Noone here calibrates just for the lulz, trust me.
[Atrix 4G General] Zeljko1234:
Some of them solve problem, but if you've read all post, some not. I've just shared my experiences. Maybe some could find it useful. You don't need to argue with me ;)
[Atrix 4G General] xploited:
I realize that not everyone needs to calibrate and I never said that everyone should.

The information is here for those that need it, and the judgement is on everyone to decide themselves if it's needed or not. :)
[Atrix 4G General] edgeicator:
And, debunked.

https://plus.google.com/u/0/105051985738280261832/posts/FV3LVtdVxPT

Battery callibration does absolutely nothing but eat more charge/discharge cycles from your battery.

I believe this should be enough evidence to prove that you were wrong when we debated whether your guide here helped or harmed your battery.
[Atrix 4G General] FULLTIMEIT:
thanks for the guide
[Atrix 4G General] xploited:
Guys, I am not going to argue with you. If you strongly believe this somehow hurts your battery - just don't use the guide, simple. That's why there's a "Disclaimer" as the very first line in the OP.

It has helped me and other people in solving specific battery problems, but it might not work for you. You are free to write your own guide and I will be sure to check it out.

p.s. The argument was between "wiping battery stats - helpful or hurtful". Ironically, in the article you linked, nowhere does it say that wiping battery stats "uses up charge cycles". All it said is that the file is used solely for statistics. Yet, you have come here to victoriously claim that you "won" or something. If this was some sort of competition for you, then you are free to consider you won I guess.

I personally posted this to help people and at this I have been more or less successful.
[Atrix 4G General] Zeljko1234:
Uhhh, nobody argue with you. Especially not me. I just wont to say that calibrating every day or often will reduce battery life.

Calibration make sense for Android itself, to learn real capacity. Nothing more or nothing less.

Trick with removing battery with charger plugged in is very, very usefull!!! Thank you for that ;)
[Atrix 4G General] edgeicator:
Your guide states this:

Are you really going to argue that this doesn't hurt your battery? As this android dev stated, wiping battery stats does absolutely nothing. In fact, the stats get wiped every single time you fully charge your battery. What you are suggesting in your guide is pure superstition. Nothing in your guide actually helps battery life besides the CWM battery fix and even that has yet to be proven it does anything meaningful.
[Atrix 4G General] xploited:
No it doesn't. And like I said, I am not going to argue with you.
[Atrix 4G General] kennethpenn:
Nobody is forced to follow these procedures. Please stop fighting in the thread.
[Atrix 4G General] Sponz:
Just a question...

Ok... first of all, amazing guide.

Just did all the steps, and now my bat is at 4200mv when fully charged.

I just have one question... after I did all the steps, and finally umpluged my phone from the charger, I had to turn it off when it was at 50% battery life (had to go to a work meeting where cel phones were asked to be turned off)

So my timeline on the steps were:

-fully charged

-checked mv on calibration app

-fully used bat, phone tuned off by itself

-fully charged with phone off

-took off battery (my phone didnt reset, just turned off on this step, so I just turned it on with no bat and waited to the ? battery)

-put battery back and waited 3 hours

-turned phone on, went to cwm wiped cache/dalvik installed jug bat fix, wiped battery stats, rebooted phone

-used phone untill bat life was at 50% then I had to turn phone off for about 30 mins

-turned back on

so after all that, did I compromised the callibration process? cause I figured that after all the steps you still had to let phone make a full discharge, and then a full recharge.

Hope I'm wrong.

Thx in advance, and sry about the wall of text (tryed my best to explain in details)
[Atrix 4G General] Zeljko1234:
You are really self-confident for someone who write MV (megavolts?) instead mV (millivolts). As I said, thank you for your guide, but you should really read something about electrical engineering, batteries, internal resistance, chemistry... before advice people.

To be honest, only trick with removing battery with charger plugged in and phone turned off make sense. Again, really thank you for that. Rest of the guide will just harm battery chemistry, increase internal resistance, short battery life and capacity. Thats are scientific facts.

You and everyone really should read, How to Prolong Lithium-based Batteries and rest of the articles on site.

Please understand, this is not attack to you. I just wish to help you and rest of the community to understand more ;)
[Atrix 4G General] xploited:
I think everything should be alright. It's not that important to follow the guide exactly as it's written. The important steps imho are CWM battery fix, wiping stats and pulling battery.

The strange part is where you say the phone didn't reboot after pulling the battery. It should have rebooted, if you gave it time, and gotten to a "battery missing" screen.

But anyway, if you got to 4200 mv at 100% then you calibrated successfully.

Just wait a day or two and see how your batter life is.

LOL! You are replying to a moderator. :D:D:D

He didn't write this guide.
[Atrix 4G General] Zeljko1234:
Ok, my mistake. But you should, no, you must read what I wrote!!! Read the f*cking link I gave you. Stop thinking that you know everything because you're continuing to give wrong advice!

Obviously, you don't know what are writing!

MV, mv and so on are LOL :D:D:D

[ROM] CM9 a multidevice collaboration by multiple devs 2/16/2012

I'm currently running an ICS rom on my atrix and am having battery issues (won't charge past 85%) will this tutorial work on it?

The tutorial says "Prerequisites:

1. Atrix on one of the rooted 2.3.4 roms (ideally,- deodexed and with unlocked CWM)"

Does it matter if I'm on 4.0.3 rather than 2.3.4?

Thanks!
[Atrix 4G General] Zeljko1234:
It doesn't matter. For quick solution, just charge it with charger, live charger connected, turn off, remove battery, wait for question mark, plug in battery and charge half/one hour.

Do not flash anything.
[Atrix 4G General] scarbutt11:
So I have a crazy problem, after taking out the battery, getting the question mark, and putting the battery back in for an hour, it never charged past 5%. Wiped battery stats and booted. Phone says I only have a 5% charge at 4200mV.

I'm confused?!?!?!
[Atrix 4G General] Zeljko1234:
Hmmm, that's strange. It's normal that phone will not charge more then 5% or 10% if is turned off. After you turn it on and boot should be about 100%.

Just disconnect charger and try to use it normally. ICS should recognize real percent after a while. You can also try factory reset.
[Atrix 4G General] scarbutt11:
Yeah I am just leaving to head to class. I'll give it some time to see if it dies or not. I can try a factory reset too.

Thanks!

Edit: I went ahead and wiped everything and reflashed my rom and everything is back to normal. And my battery seems to be working better too!
[Atrix 4G General] Mr_quatdien:
Thanks.

That so great!!!!
[Atrix 4G General] diuface:
Great post! Fixed my battery issues.
[Atrix 4G General] killinme1:
This works great, calibrating gave me another 800ma. Don't get obsessed with the processes you have running. If your phone is achieving deep sleep then fiddle with wakelocks and running processes slowly, reboot after a change and monitor batt stats, just going in full bore and shutting down a bunch of stuff will most likely lead to more problems.
[Atrix 4G General] RFOX100:
thanks really helped me .. thought i had lots of problem with the battery but i was wrong. battery is just fine . 100% with 4200.

thanks

Tnx for the How To. I'll looking for it when I'm going through this problems.

Thanks for this tip!! Been looking for a comprehensive guide like this... just noticed it after scrolling through a few pages in the section. Will try it soon!! My battery is fine for now tho... but I can't reach 100%, only 98...
[Atrix 4G General] yang123:
Thank you so much. These simple steps fixed my 85% battery problem.

charge it with charger, live charger connected, turn off, remove battery, wait for question mark, plug in battery... it then showed 5%, I unplug the charger and unplug the battery for 30 sec, put back the battery and turn on the phone.. it is now 100%
[Atrix 4G General] muhski:
Hey guys!

I followed this guide to the step when I checke my voltage with the battery-app.

It says 4200mv at 100% so I stopped following this guide.

I flashed the battery fix and let the battery-app calibrate my battery. Started watchdog to check which process is sucking on my battery and here it is:

"suspend"

Linux process...

Any idea what it is? Without data and Wifi I loose around 14% battery at night.

But I want to switch one of it on (whatsapp) to get notifications...

I think I dont need to finish the steps of this guide because my battery seems ok, right?
[Atrix 4G General] :
Are you using a task killer?

Sent from my MB860 CM7 olympus always latest nightly 37p Radio.
[Atrix 4G General] xploited:
Your phone shows 4200mv at 100%, meaning it's fully calibrated, so no reason to worry about that.

Losing 14% at night does seem slightly higher than it should be.

I think suspend process is related to power management / sleep. Which ROM are you using?
[Atrix 4G General] muhski:
No, no task killer...

Latest Neutrino CM7 EE-Rom with the 1Ghz Faux Kernel...

But 14% over night with only network connection on?!

With my Xperia Play i lost around 2-4% :(

Oh and when I text a lot over WiFi (whatsapp) or play games (even simple ones), the phone gets warm very quick...
[Atrix 4G General] xploited:
There's definitely something draining your battery. EE Neutrino is probably the best ROM for battery life around.

Are you using stock EE kernel? Also, which radio version are you running? Are you sure you don't have any known battery hogging apps like Facebook, etc? :D
[Atrix 4G General] xxLHRxx:
Same issu here. Using Neutrino EE, and "suspend process" eating almost entire battery life. Don't know what to do anymore.
[Atrix 4G General] muhski:
yes, ee stock kernel. no such apps... had the issues right from the beginnig (one week ago).

I tried many radios because of this problem, so right now I'm on N.1.100.R China retail (i'm in china right now), so that works best with my network and wifi...

Most of the radios don't even get connection!

maybe I should try a new kernel?!
[Atrix 4G General] soudy1994:
does jug6ernaut's CWM battery fix work with cm 9?
[Atrix 4G General] amnher:
is there a way to apply this on W8/X8 E16i(Sorry for posting about different device)

Cause my phone never reaches 4200mV at 100% maybe 4180mV and as soon as I unplug at, it drops to about 4150-4160mV instantly. is that normal?
[Atrix 4G General] Zeljko1234:
It's normal. Don't worry about 20mV. Calculate percentage and you will see is not that much :) Battery doesn't like to bee at maximum anyway.
[Atrix 4G General] Cusa:
My phone goes up to 4207mv, very weird.
[Atrix 4G General] Zeljko1234:
Again, it's just 7mV. Don't worry. Unplug and you'll see immediately is lower :)
[Atrix 4G General] kisposi:
Hi!

Is it ok that battery monitor pro shows that my battery has 1880mAh? I thinik it should be 1930mAh. Once I made a backup restore, from that time my battery life is not that good.
[Atrix 4G General] Apex:
Without going through all the pages in this thread, and with the understanding that this may be both a stupid question and one that has likely been asked previously for this method, but will this work (or a variation of) on the Atrix 2 MB865?
[Atrix 4G General] nh777:
I've tried several times to pull the battery while still being charged but I never saw the "missing battery" icon.

What happens is that the led turns green, the screen appears to come on (although still black), and the device dies before rebooting to the same process, over and over.

This happened after fully charging, again after clearing battery stats, etc.

The phone appears to be charging fully now to 100% (after only getting up to 80% after being fully discharged before), but should I be concerned the the icon doesn't show up?
[Atrix 4G General] clod007:
Phone into the wall and remove the battery and then wait logo with question mark icon.

Can not wait (i find impossible not to appear).

Then insert the battery.

In my opinion, screen on for 5-7 hour is very good battery life.
[Atrix 4G General] nh777:
I did exactly that.

Phone is off and plugged into wall. I remove the battery. Green LED comes on, screen turns on (but black), and a few seconds later it shuts off and turns on again. It keeps going on/off for minutes. Never see the question mark icon.

I can't imagine this has anything to do with the rom, but I'm using Neutrino if it means anything.
[Atrix 4G General] bimasakti85:
No need to do the pull off battery anymore. Just delete the file inside battd folder (/data/battd) and then reboot. Before that, charge your battery until it doesnt increase anymore for example at 94%...
[Atrix 4G General] nh777:
Thanks. I'll give that a try tomorrow once I get a full charge and will update this post.

Edit: Only got up to 95% even though it was fully charged. Went into /battd but saw there was more than one file to delete, so I rebooted into recovery, cleared batt stats, rebooted to 100%, and calibrated. Later, I found that you meant that I should delete everything inside the battd folder but "uid." I'm glad I held off but at least I know now.
[Atrix 4G General] clod007:
Thousand excuses. But i'm curious. How you worry about your battery.

Keep my screen lit 7-8 hours with 6-7 hours and 2,5-3 days for only 1,5 hours talk. (CM7 rom)

Do not worry about nothing? So can the Atrix.
[Atrix 4G General] nh777:
I didn't have an issue with battery life, that wasn't my worry. When I installed a new rom, I noticed the calibration was off. 12 hours of charging and it maxed out at 80%. mV was fine at ~4200.
[Atrix 4G General] clod007:
Ok, sorry! You have already received the reboot solution. Success!
[Atrix 4G General] voncount:
My atrix have 2 batteries and charger dock. All i have to do just fully charge 2nd battery, put in on my phone & wipe battery stats then do the same thing with the other.

No any battery saver apps, no any scripts, my phone is always up to 2 days using with only 1 batt.

It is very very better than my old phones as LG nitro HD, sensation, desire.
[Atrix 4G General] James62370:
From what I recall this happens if you are using an overclocked kernel. Try a stock kernel. You can always reflash an oc kernel afterwards. Good luck.
[Atrix 4G General] nh777:
Weird. I'm running different roms like Neutrino and epinter's CM10 without touching the kernel and yet others seem to have no trouble with it showing up.

Any thoughts if flashing the stock 2.3.6 kernel would somehow also help with my battery calibration issues, ie, get the percentage past xx% even though mv shows ~4200?

How much should my battery show when completely drained?

Its still showing around 3600Mv's, is this correct?

thanks for any help

Jonnym
[Atrix 4G General] ravilov:
Mine is currently at 3% and shows 3569mV. But that depends on a lot of things. Every battery is different and every system is different.

EDIT: currently at 1% and shows 3218mV. I think it's the lowest I've ever had. Still waiting for the phone to die.

Not sure if this is good for the battery, but at this point I'm just wondering how low can it go. :)

Will wait until the phone shuts down on its own.

EDIT 2: LOL, it just happened. It shut down at 3218mV.
[Atrix 4G General] Zeljko1234:
Li-ion operates from 3200 to 4200mV. Depends of age of battery with some (high) current (because of internal resistance), voltage will drop under 3200mV and phone will shut down. Over time internal resistance increases.
[Atrix 4G General] Zhero.ar:
Battery hot and swollen -> broken!

Just wanted to say I was watching videos trying to drain the battery to perform these steps until the phone was turned off normally. When I try to reload it I see that I couldn't. I took out the battery and noticed it was hot and swollen. Now doesn't work anymore.

While I believe that my battery was not working quite right, I've read that the Atrix has problems with the battery overheating. Keep an eye on it.

I was using a fuitcake rom 2.3.4.

So...quick question. When we set the threshold in watchdog to 20%, do we leave this setting at 20% , or switch it back everyday?

Sent from my Evolved EVO ;)
[Atrix 4G General] dictoresno:
i had 4198mv before the calibration. i think mine was properly calibrated from last time.
[Atrix 4G General] dictoresno:
dude, your display usage is only 12%......i left my phone nearly idle for 3 days, playing with it for a little here and there, and it took almost 4 days to die. this just seems like u barely used the phone at all. bad example.
[Atrix 4G General] pousson4:
Alot of my battery issues were fixed by flashing the ATT .91 Radio http://www.multiupload.com/N25DIPNAU6 from samcripp. I had flashed Ken's Beta, then Ninja and somehow didn't get the radio from either (they might not actually have it in the build.....I didn't check) and was still on the 1.83 radio. Battery life is upwards of two days now with moderate use and speeds are spiking around 5Mbs, with constant 3Mbs down.
[Atrix 4G General] dictoresno:
well i did the fix again. upon immediately unplugging the phone, i drop to 99%. i dont know if thats from the 1% battery mod or not. but i show it drop from 4198mv at 100% to 4167mv at 99%. i guess time will tell.

EDIT: after 40 mins of the phone in airplane mode but connected to wifi and little use (mostly idle) im showing 97% now. seems like its still mis-reporting battery life. on reboot, it jumps back to 99% but the mv still shows it decreased to 4106mv from 4198mv.

does anyone else have this issue?? where is this battery reporting issue present, all 2.3.4 builds????
[Atrix 4G General] xploited:
After the calibration process you can restore the thresholds to default, or even uninstall WatchDog (if the overnight draining problem is fixed) .
[Atrix 4G General] xploited:
Not for me. I started having battery drainage and drops depite being on .91 radio from day one. But the calibration fixed it for me. :cool:
[Atrix 4G General] xploited:
First of all, drop 99% is a common thing. It shouldn't affect your battery life by any noticeable margin.

Emm, dude, 3hrs of display is not what one would call "letting the phone nearly idle". Second i'm not trying to say that i tried to drain my battery with heavy usage and it didn't, i'm just saying that untill πCrust i had tried stock gb releases and Ninja custom, all had like 3-4%/hr drop when idle, in this rom bat just doesn't drop. But also when surfing or playing games the difference is obvious.

Not trying to impress. I'm just comparing now and same usage before. The difference is huge, at least for me.
[Atrix 4G General] xploited:
Guys, this thread is not about competing who has better battery life, we are limited by the same battery, from there on it depends on your software setup and how you use it.

This thread is mostly for people that have draining / % jumping issues and partially for those who want to recalibrate.
[Atrix 4G General] dictoresno:
12% of display time seemed small, until i realized again it was 12% of 2+ days of use. thats not bad afterall.
[Atrix 4G General] SS2006:
Step 16

16. Make sure your wifi and data connections are off. Now finally unplug the phone from the charger.

Why?? If i have wifi on itll break something?
[Atrix 4G General] xploited:
I recommend doing this for a "clean test" of how much battery % your phone loses overnight.

If you absolutely must have internet always on, then feel free to leave it on. Your phone still shouldn't lose more than 10-20% overnight, depending on how actively it's accessing the network.
[Atrix 4G General] nexxusty:

Worked well for me. I was at 4000mv when I started and after I was at 4200MV. Gaining 200mv makes me happy. I am positive my battery is where it should be.
[Atrix 4G General] kewljay223:
i am have these symtoms as well but you say that in order to use the fix the phone needs to be on a custom rom...preferably deodexed. well im still using the stock 4.5.91 OTA update. is it safe for me to do this?
[Atrix 4G General] wintermute000:
you can't break anything, worst case you'll mess up battery stats which you can always wipe (in recovery or with root, you don't need a unlocked bootloader).

You need at least root or a custom recovery though that will let you wipe battery stats.
